Let's divide 543429 by 30
We want to figure out the number of times 543429 can be divided by 30.

Moving on to step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 30

Going ahead to step 2:
When dividing 54 by 30, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 54 to get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 30

Step 3:
When dividing 243 by 30, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 240 from 243, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 30

Moving on to step 4:
30 goes into 34 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Subtracting 30 from 34 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 30

On to step 5:
If we divide 42 by 30, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1811.0
Subtract 30 from 42 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 30

Advancing to step 6:
30 can be fit into 129 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 18114.0
Subtract 120 from 129 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 30, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 18114.3
If we take 90 away from 90, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18114.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18114.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 18114.3 with a remaining 0.0.
